Question
Answer
$$4w^2-w-2-7w+5=4w^2-8w+3$$
Explanation
| $$ \begin{aligned}4w^2-w-2-7w+5& \xlongequal{ \color{blue}{ \text{\normalsize{ \htmlClass{explanationCircle explanationCircle1}{\textcircled {1}} } }}}4w^2-8w+3\end{aligned} $$ | |
| ① | Combine like terms: $$ 4w^2 \color{blue}{-w} \color{red}{-2} \color{blue}{-7w} + \color{red}{5} = 4w^2 \color{blue}{-8w} + \color{red}{3} $$ |
